A word from Shelley, the 'Dark Enchantress' costume creator:

This was my spin on the evil enchantress. The headpiece was made from black craft foam and deco wire. I then added the details of the raven skull, beads, gems, horns and feathers. The horns were from Walmart for about 2.00 and the feathers were from a piece that I had purchased from Party City last year during Halloween clearance. The corset, sleeves and overdress were purchased as one piece...I sewed feathers to the tops of the sleeves, added the hanging chains and small mink skulls to the corset. The under skirt was from a previous steam punk Pokemon costume I had done a couple of years ago. I made a fake sword sheath using a piece of cardboard and a plastic sword handle which I covered in pieces of faux leather from a jacket bought at the thrift store. The feather piece on the sword sheath is the other part of the feather piece used on the head piece. I added the raccoon skull and a leather tong wrap.
The necklace was a Halloween bat necklace worked into a lace choker. The staff was a purchase from a renaissance festival years ago.
